Overview
PC341-W helps you monitor the amount of electricity Consumed and Produced in your facility by connecting the clamp on to the power cable. Monitor whole home Energy and up to 16 individual circuits.
Key Features
- Single, Split-Phase 120/240VAC, 3-Phase/4-wire 480Y/277VAC electricity system compatible.
- Remotely monitor whole home Energy and up to 16 individual circuits with 50A Sub CT, like Solar, lighting, receptacles.
- Bi-Directional measurement: Show how much energy you are producing, energy consumed and excess energy back to the grid.
- Real-time Voltage, Current, PowerFactor, ActivePower, Frequency measurement.
- Historical data of Energy Consumed and Energy Production is displayed in Day, Month, Year.
- External antenna prevents signal from being shielded.
Standard models: Split-Phase (US): PC341-2M-W, PC341-2M16S-W. Three-Phase (EU): PC341-3M-W, PC341-3M16S-W.
